Great Gods help me ~~~~~

Go to the interfaces of google or Baidu

All of these interfaces are skipped and then jumped back. what I want is mutual conversion like function encryption.

Short URL, which is controlled by others, you can use the API long URL for query.
For example, bitly.com
It's API documentation in http://dev.bitly.com/links.html

I felt slow when I used Baidu APIs for batch Conversion. Is it wrong?

function dwz($url){$ch=curl_init();curl_setopt($ch,CURLOPT_URL,"http://dwz.cn/create.php");curl_setopt($ch,CURLOPT_POST,true);curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);$data=array('url'=>$url);curl_setopt($ch,CURLOPT_POSTFIELDS,$data);$strRes=curl_exec($ch);curl_close($ch);$arrResponse=json_decode($strRes,true);if($arrResponse['status']==0){echo iconv('UTF-8','GBK',$arrResponse['err_msg'])."\n";}return $arrResponse['tinyurl'];}for($i=1;$i<=10;$i++){echo "http://zhidao.baidu.com/question/".rand(0,100000)."$i.html----->".url_short("http://zhidao.baidu.com/question/".rand(0,100000)."$i.html")."
";}

Thank you for your help ~~~

The code you wrote above has a problem, and we don't see where dwz is used.

Mutual transfer of long and short URLs
Long to short, short to long is not reversible
I don't think it is a one-to-one ing. it cannot be implemented without third-party storage mappings.

Third-party storage is not required, unless you apply for a domain name, and then perform a database comparison, a column of Long addresses, and a column of short addresses. you need to query the database when necessary, however, almost all domain names with a short URL cannot be applied for now.

Sorry, I am stuck wrong.

Function dwz ($ url) {$ ch = curl_init (); curl_setopt ($ ch, CURLOPT_URL, "http://dwz.cn/create.php"); curl_setopt ($ ch, CURLOPT_POST, true ); curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, true); $ data = array ('URL' => $ url); curl_setopt ($ ch, CURLOPT_POSTFIELDS, $ data ); $ strRes = curl_exec ($ ch); curl_close ($ ch); $ arrResponse = json_decode ($ strRes, true); if ($ arrResponse ['status'] = 0) {/** error handling */echo iconv ('utf-8', 'gbk', $ arrResponse ['err _ msg ']). "\ n";} return $ arrResponse ['tinyurl'];} for ($ I = 1; $ I <= 10; $ I ++) {echo "http://zhidao.baidu.com/question ". rand (0,100000 ). "polici.html -----> ". dwz ("http://zhidao.baidu.com/question ". rand (0,100000 ). "ii.html ")."
";}

Can I use other methods besides databases?

Currently, it is implemented using the database method. I want to know if there are other methods for implementation.
